Abstract：A new method for the preparation of TiO2 dual-modified by transition metal doping and carbon nanotube (CNT) grafting was proposed. Fe-NiO/TiO2 was prepared by sol-gel method. Then CNTs were grafted on Fe-NiO/TiO2 by fluidized bed chemical vapor deposition (FBCVD) method. The dual-modified CNT/Fe-Ni/TiO2 composite photocatalyst has been characterized by X-ray diffraction (XRD), Raman spectra, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), UV-Vis absorption spectra and photoluminescence spectra. The photocatalytic activities of prepared samples were investigated by the photodegradation of methylene blue (MB). The results show that CNT grafted on TiO2 had good graphite structure, and small part of TiO2 was transformed from anatase to rutile during FBCVD process. Double modification of transition metals and CNT can effectively overcome intrinsic defects of TiO2 in small specific surface area and low quantum efficiency. And the photocatalytic activity has been improved significantly.
